So I have decided it's time go ahead and finally replace all the plastic cooling pieces to my '03 LS8. I Have gotten a general parts list from Choco in this thread. http://www.lincolnvscadillac.com/forum/showthread.php?76454-Engine-overheat "Degas bottle Upper radiator hose Lower radiator hose Thermostat housing Thermostat housing cover Thermostat Small host that goes from upper radiator hose to dccv (AutoZone 5 bucks) 2 Small hides ontop of thermostat housing (AutoZone 5 bucks) Hose that goes from degas bottle to the connector (AutoZone 8 bucks) Thermostat rubber washers x2 Thermostat cover washer " Now my main concern is the fact that I don't want to be half way through this procedure and need to order more parts and pieces. I'd assume that the "seals" that I need to replace are specific to the Lincoln LS.. or are these "seals" that everyone refers to a generic sized o-ring seal that I can pick up at autozone? And by "seals" I'm referring to the comment people make on overheating threads "you need to replace the plastic cooling parts and the various seals as well". I just want to be sure I have everything I need before I tackle this. Also I'm aware that there are 926 million "overheating" threads raping the LS forum, so I apologize for another contribution. Oh and just because I may be asked, I've owned my LS for only 1700miles, and it overheated (needle read 10oclock position, about 3/4 on temp) and I've only used the car to commute to work which is 2miles each way. Car barely gets to operating temp, and has never overheated but that one time. Anyhow I'm ready to fix this because I want the peace of mind before I really drive her. So yeah, if you guys could give me some insight on this "seals" question, and/or just some input to help me be sure I've acquired all the parts I need before I do the install, I'd greatly appreciate it. God bless you all and goodnight!!
